DYOP

 
Home
DYOP stands for DYnamic OPtotypes and is a new way to show a bilaterally symmetric optotype ring with forced-choice, 2-way selection of a moving striated ring versus a static ring. DYOP correlates with standard LEA and Snellen acuity for adults and fairly young children with a Forced Preferential Looking option for young children.
